r - 如何设置testthat以进行R CMD检查？

Question

显然，有两种方法可以将testthat与R CMD check集成在一起。我都不能上类。

方法1 :(可能已弃用)

根据devtools wiki:

When developing a package, put your tests in inst/tests and then create a file tests/run-all.R (note that it must be a capital R), which contains the following code:

library(testthat) 
library(mypackage)
test_package("mypackage") 

This will evaluate your tests in the package namespace (so you can test non-exported functions), and it will throw an error if there are any test failures. This means you'll see the full report of test failures and R CMD check won't pass unless all tests pass.

整个包是 here。其中有两个文件:

## minimalbugexample/inst/tests/run-all.R
library(testthat)
library(minimalbugexample)
test_package('minimalbugexample')

和

## minimalbugexample/inst/tests/test-use-Matrix-package.R
context("Intentional break")
  expect_that( TRUE, equals(FALSE))

我的描述是

Package: minimalbugexample
Title: 
Description: 
Version: 0.1.1
Author: Nathan VanHoudnos <nathanvan@letterafterFmail.com>
Maintainer: Nathan VanHoudnos <nathanvan@letterafterFmail.com>
Depends:
    R (>= 3.0.1),
    Matrix (>= 1.0)
Suggests:
    testthat
License: GPL
LazyData: true
Collate:
    'minimalbugexample-package.r'
    'use-Matrix-package.R'

安装软件包后，我可以很好地运行测试(它们按预期失败)。

> test_package('minimalbugexample')
Intentional break : 1


1. Failure:  -------------------------------------------------------------------
TRUE not equal to FALSE
1 element mismatch
Error: Test failures
> 

但是 R CMD check无法运行测试。

$ R CMD check minimalbugexample_0.1.1.tar.gz 
... snip ...
* checking PDF version of manual ... WARNING
WARNING: There was 1 warning.
See
  ‘/home/nathanvan/software/minimalbugexample.Rcheck/00check.log’
for details.

我认为PDF警告与此无关，但是如果需要，我可以提供更多详细信息。

方法2 :(出血边缘)

根据 README file of the testthat repository:

Now, recommend practice is to put your tests in tests/testthat, and ensure R CMD check runs then by putting the following code in tests/test-all.R:

library(testthat)
test_check(yourpackage)

因此，我确保已安装了最新版本的test:

> install_github("testthat")

然后换包。您可以获取此版本 here。我将两个文件修改为

## minimalbugexample/inst/tests/test-all.R
library(testthat)
test_check(minimalbugexample)

和

## minimalbugexample/inst/tests/testthat/test-use-Matrix-package.R
context("Intentional break")
  expect_that( TRUE, equals(FALSE))

然后将DESCRIPTION文件中的软件包版本更新为0.1.2，我可以对其进行构建，安装并使用 testthat进行检查并获得与之前相同的输出。因此，就 testthat而言，它似乎可以正常工作。

但是，R CMD检查仍然无法运行测试:

$ R CMD check minimalbugexample_0.1.2.tar.gz 
... snip ...
* checking PDF version of manual ... WARNING
LaTeX errors when creating PDF version.
This typically indicates Rd problems.
WARNING: There was 1 warning.
See
  ‘/home/nathanvan/software/minimalbugexample.Rcheck/00check.log’
for details.

所以问题是:

我究竟做错了什么？我更喜欢方法2的解决方案，但我要么接受!

Answer 1

您没有tests目录。 test-all.R应该位于minimalbugexample/tests/test-all.R。

然后，您的实际测试将使用方法1的minimalbugexample/inst/tests或方法2的minimalbugexample/tests/testthat/。

对于方法2，test-all.R文件应使用test_check(yourpackage)而不是test_package(yourpackage)，并且不再需要library(yourpackage)调用。
